With guidance maybe a good product

The blank is because without guidance. It has given neither the new blank, even when the original key an idea of ​​how the mechanical key from or into the housing. Result defective with me, and original key blank. Now I can use my spare key, which is not collapsible and have additionally the Fernbedinung without mechanical keys, hanging at home, on a key chain.
As I said, with a guide, this might not have happened.

Addendum 11.06.2014:
Got the seller a new blank.
At first I wanted to replace the complete mechanical key. But then I noticed the small studs. With a hammer and small punch, I removed the original and the blank pins. Original key in the blank, caution purely hammering studs. Done. This saves the hassle with the spring mechanism and many nervous.
